Well, if you want to keep using red power, I'd suggest you use filters.
So you start out by laying out a line of tubes, pulling items out of your quarry chest with a sorting machine or filter. Don't color your items here.
Along the long tube, you place filters which point to chests. Inside the filters you put the items you want sorted to those chests.
At the end of the tube you have an overflow chest/mechanism.
So all items will be send through the main tube, the filters will act as the first valid destination for the chosen items. The chest at the end will receive anything which can't go into the filters.
Optionally, you can change the filters with sorting machines if you want to filter more than 9 items to a chest.
